Jimmy Fallon's lip-synch battles have long been an institution on his shows. But we don't know how he'll top this one.

Emma Stone paid a visit to The Tonight Show Monday, and she came prepared. That is to say, she came prepared to rap Ludacris's hyper-fast part on DJ Khaled's "All I Do Is Win." By the end of her performance, the title certainly seemed apt.

Fallon called it the "the best one [lip-synching performance] that's ever been done on the show ever," and we're inclined to agree.
